Whether it’s on Mars or at the kitchen table, entrepreneur Bart Womack wants to change what and how you eat.

But the CEO and founder of next-generation farming startup Eden Grow Systems is seeking crowdfunders to help feed the venture.

The company evokes images of a garden paradise on earth. But the idea behind the Houston-based NASA spinoff came from a more pragmatic view of the world. Womack’s company sells indoor food towers, self-contained, modular plant growth systems built on years of research by NASA scientists looking for the best way to feed astronauts in space.

The company has launched a $1.24 million regulated crowdfunding campaign to raise the money it needs to scale and expand manufacturing outside the current location in Washington state.

Additionally, the U.S. Air Force recently chose Eden as a food source for the U.S. Space Force base on remote Ascension Island, in the Atlantic Ocean, Womack tells InnovationMap. Another project with Space Center Houston is also in the works.

“We want to be the government and DOD contractor for these kind of next-generation farming systems,” he says.

The Houston-based company includes former NASA scientists, like recent hire Dr. L. Marshall Porterfield, of Purdue University, as an innovation advisor.

Womack, a former digital marketer, Houston public channel show host, night club owner and entertainment entrepreneur, left those ventures in 2012, after the birth of his first child. While taking a year to study trends research, in 2014, what he read intrigued and alarmed him.

“I’ll never forget, I came across a report from Chase Manhattan Bank….of the top 10 disruptive investment sectors, over the next decade,” he says. “At the very top of the list was food.”

His conclusions on the fragility of the world’s food supply system, due to overpopulation, and scarcer land, led him to launch Eden in 2017, funded by venture capital firm SpaceFund, Womack, his family, friends and angel investors.

Womack believes “black swan” events will only increase, disrupting the food supply system and further jeopardizing food supplies.

“We’re going to enter a period of hyper novelty in history,” Womack says.. "The system we’ve built for the last 100 years, the super optimized system, is going to begin to break apart."

To avert a centralized food production outcome, operated by corporate giants like Amazon or Walmart, Womack’s vision offers a decentralized alternative, leaving it in local hands.

With $2 million put into the company so far and a half million-dollars in sales last year, Womack argues that Eden has achieved much and can make food independence within reach for everyday families.

The company commercialized NASA technology to fill what it viewed as “a huge gap within the controlled…agricultural space.”

The tower is the building block of a modular, automated and vertical indoor plant growth system, with calibrated misting, fans, and LED lighting, controlled by an app.

The company website touts the towers as an easy way to grow plants like lettuce, carrots, tomatoes, and potatoes, with little water, no soil, and lots of air, without the expense and work of cultivating an earth-based garden.

For those who want to eat more than greens, the towers provide a way to breed fish and shrimp in an aquaponic version, recycling fish waste as plant fertilizer.

However, big plans come with big costs. The towers range in price from $5,000 to $7,000, although payment plans for those who qualify make it affordable.

Eden has sold around 100 of their towers so far, to a variety of customers. But rising costs and shipping delays have led to a a three-month backlog.

The manufacturing and shipping associated with larger installations means that even if the company made a million-dollar sale, delivery of the product would take a year.

“One of the hardest things…as a start-up, the last couple of years, is trying to narrow down exactly where the biggest payback is,” Womack says. “There is the lower hanging fruit, of small sales to individual buyers, but there’s the larger fruit of institutional buyers. But they can take months and years to convert into an actual buyer.”

Customers include several universities, including Texas A&M University and Prairie View A&M University, and talks are underway with other large academic institutions.

For now, attracting investors so the company can reach its funding goal poses the biggest challenge.

“Texas investors are very, very hard-nosed, and they’re not like West Coast investors. They want to understand exactly how they’re going to get their money back, and exactly how quickly,” he says.

Womack says the crowdfunding round would allow the company to expand manufacturing operations into Houston, deliver product faster, and invest in advertising.

“When we complete this round, and become completely self sufficient, we’re planning on moving to a $25 million valuation,” Womack says. “We can show, given money, we can scale the company.”

The city of Nassau Bay, next to NASA’s Johnson Space Center, has purchased towers and plans to purchase more, not for the production of food, but to grow ornamental flowers.

Womack says that city officials there found that it’s cheaper to grow the decorative plants themselves, rather than buying them.

The towers are adaptable, and can grow not only food but cannabis and other plants, and if buyers want to use them other purposes, that adds to the product’s appeal, Womack says.

Eden has also sold some towers to Harris County Precinct 2 and the city of Houston, as part of a project he says will turn food deserts throughout the area into “food prosperity zones.”

“Our goal is to be the farming equivalent of Boeing,” Womack says.

Electric truck charging network expands to Houston-Dallas freight corridor

electric trucking

Greenlane Infrastructure, an electric public charging station developer and operator, is expanding outside of its home state of California and into Texas.

The Santa Monica-based company plans to launch its high-power charging sites along the Dallas–Houston I-45 corridor, which is one of the highest-volume commercial trucking routes in the country, according to a news release from Greenlane.

The sites will feature 6-8 pull-through lanes with chargers supporting combined charging system (CCS) and megawatt charging system (MCS) connectors that allow electric truck drivers to recharge their vehicles during standard rest periods. They will also offer tractor parking and charging, as well as operations that will allow for overnight stops.

Drivers can reserve chargers in advance, monitor charging activity in real time, and manage billing from the Greenlane Edge platform.

“Our customers are making commitments to electrify their fleets, and they need a charging network that can grow alongside them,” Patrick Macdonald-King, CEO of Greenlane, said in the release. “This is the first leg of the Texas triangle, one of the more important freight arteries in the country, so bringing high-power charging there is the next logical step in building a network that serves how freight moves across America.”

Greenlane is also expanding across the West Coast, with five locations under development in California and Nevada. It opened its flagship Greenlane Center in Colton, California, in April 2025. The company plans to open locations in Blythe, California, and Port of Long Beach this year.

Greelane was founded in 2023 as a joint venture between Daimler Truck North America, NextEra Energy Resources and BlackRock. It has secured partnerships with electric long-haul truck developer Windrose Technology, Velocity Truck Centers and Volvo Trucks North America.

Houston startup lands $1B from Blackstone and Halliburton, plans acquisition

power deal

Houston-based power generation startup VoltaGrid has nailed down a $1 billion equity investment from asset management heavyweight Blackstone and Houston-based oilfield services provider Halliburton.

The investment comes in two forms:

  • A $775 million primary capital raise
  • A $225 million secondary capital purchase from existing investors

VoltaGrid, founded in 2020, provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.

Aside from the $1 billion investment, VoltaGrid has agreed to buy Propell Energy Technology, a VoltaGrid supplier, for an undisclosed amount. Propell offers a natural gas power generation platform for AI data centers. VoltaGrid plans to add two manufacturing plants at Propell’s facilities in Granbury, a Dallas-Fort Worth suburb.

The investment and acquisition deals are expected to close in mid-2026.

Funds managed by Blackstone Tactical Opportunities are contributing to the $1 billion investment. William Nicholson, managing director of Blackstone, called VoltaGrid “a highly differentiated platform addressing one of the most important infrastructure needs of the AI era: reliable, rapidly deployable power. This investment is a strong example of Tac Opps’ focus on providing flexible, scaled capital to exceptional entrepreneurs and businesses operating in Blackstone’s highest-conviction investment themes.”

Nathan Ough, founder and CEO of VoltaGrid, said in a release that the Blackstone investment “is a powerful endorsement of the platform we have built and the role VoltaGrid is playing in delivering the energy infrastructure of the AI era.”

Last October, VoltaGrid and Halliburton said they had forged a partnership to supply power for data centers around the world, with the Middle East picked as the initial target. Two months later, the companies said they had arranged the manufacturing of 400 megawatts of natural gas power systems that’ll be delivered in 2028 to support new data centers in the Eastern Hemisphere.

Jeff Miller, president and CEO of Halliburton, said his company’s investment in VoltaGrid “reflects our shared focus on long-term solutions for the world’s most demanding power environments, and advances VoltaGrid’s ability to deliver reliable, distributed power at scale.”
